PVS Software Requirements

PVS is available for the following platforms:

  • Red Hat Linux ES 5 / CentOS 5 64-bit

  • Red Hat Linux ES 6 / CentOS 6 64-bit

  • Red Hat Linux ES 7 / CentOS 7 64-bit

  • Mac OS X 10.8 and 10.9 64-bit

  • Microsoft Windows Vista, 7, 8, Server 2008, and Server 2012

Note: High Performance mode is available only on CentOS 6.x 64-bit, Red Hat ES 6.6+ 64-bit, CentOS 7.x 64-bit, and Red Hat ES 7.x 64-bit. PVS 5.1 and later running in High Performance mode is supported for Linux kernel version 2.6.34.

You can use ERSPAN to mirror traffic from one or more source ports on a virtual switch, physical switch, or router, and send the traffic to a destination IP host running PVS. The following ERSPAN virtual environments are supported for PVS:

  • VMware ERSPAN (Transparent Ethernet Bridging)
  • Cisco ERSPAN (ERSPAN Type II)

Tip: Refer to the Configuring Virtual Switches for Use with PVS document for details on configuring your virtual environment.

High Performance Mode

To run PVS in High Performance mode, you must enable HugePages support. HugePages is a performance feature of the Linux kernel and is necessary for the large memory pool allocation used for packet buffers. If your Linux kernel does not have HugePages configured at all, PVS will automatically configure HugePages per the appropriate settings. Otherwise, if your Linux kernel does have defined HugePages, refer to the Configuring HugePages instructions for PVS.

The following virtual environments are supported for PVS running in High Performance mode:

  • VMware ESXi/ESX 5.5

  • VMXNET3 network adapter
